United States Import And Export Data

The U.S. import and export data have been assembled by Robert Feenstra of the Department of Economics, under a grant from the National Science Foundation to the National Bureau of Economic Research (NBER). It is available at a highly disaggregate level called the Harmonized System (HS). The disaggregate data can be downloaded from this site in three different versions: (i) the original data from U.S. Census, 1972-1988, which is further disaggregated by port of entry and mode of transport, but comes in ASCII files that are difficult for inexperienced researchers to use; (ii) the processed data that sums across U.S. ports and modes of transport, 1972-2001, as described in the NBER working papers cited below. These data are available as ASCII files, but are much easier to use than the raw data; (iii) the processed data, 1972-2006, as described in (ii), but available as SAS or STATA files. Version (i) should be used by researchers who need the extra detail of U.S. ports and mode of transport; version (ii) should be used by those who want to look at the ASCII files with a text editor, and quickly find the import or exports detail for particular commodities; version (iii) should be used by researchers who want to immediately analyze the data with SAS or STATA.

A fourth format for the data, that can be ordered below, is: (iv) the disaggregate data available on CD-ROM, with a front-end software to select commodities. This version is suitable for libraries or students not familiar with handling large datasets, but only covers the period 1972-1994.

The disaggregate data has also been aggregated to the 4-digit Standard Industrial Classification (SIC) codes, which match the U.S. output and employment data in the NBER Productivity Database. These import and exports flows by 4-digit SIC category can be downloaded for 1972-1994. The updated import and export SIC data to 2001 is discussed in NBER Working Paper #9387, which can be downloaded below. That paper also give links to U.S. tariff data.

Working Papers

Complete documentation for these data can be found in two working papers:

  • NBER Working Paper #5515 For Import Data
  • NBER Working Paper #5990 For Export Data
  • NBER Working Paper #9387 that updates both import and export data to 2001.

1972-1994 U.S. import and exports by 4-digit SIC category

U.S. Imports and Exports by 4-digit SIC Industry, 1958-94

The files in this directory contain the U.S. import and export data according to the 4-digit Standard Industrial Classification (SIC) 1972-basis. 

It should be noted the the value of imports reported in this directory is a revised version (for the years 1989-1994) of the value of imports reported in the NBER Trade Database, Disk 1, and reported prior to February 28, 1997, at the NBER Web and FTP site. The SIC import data contained on Disk 1 should not be used. 

A complete description of these data can be found HERE. Series are divided into .Zip files that can be downloaded by selecting the appropriate link in the Data column. A brief description of the data is porvided. A detailed description can be viewed in a separate browser window by selecting theText link. Series that have been broken up into many files are listed below their description.

1987-based SIC trade data, updated to 2001, can be found at Peter Schott's website, HERE.
